To all whom it may com-era Be it known that I. JAMES \Y. Baron, a citizen of the I'nitcd States, residing at Bloomfield. in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Weighing Apparatus, of which the following is a fu l, clear, and exact description.

In apparatus for weighing commodities, and computing the cost or price, or printing the weight, or both, it is desirable, for the sake of accuracy in the com mting or printing operation, to lock the weight-actuated or controlled element or elements after the same have come to rest. The laws in force in some localities, however, forbid locking up the scale, for the reason that it opens the door to fraud upon the customer, in that material can be surreptitiously removed from the scale-pan without the fact being evidenced by the weight indicating mechanism. I have accordingly been ledto devise my present invention, which has for its chief ob ect to provide a weighing apparatus in which the weighbactuated or controlling member or mechanism that controls or sets the printing orcompnti-ng mechanism can be locked, but leaving the scale-pan and indicating mechanism free. Movement of the latter, even during the printing or com puting operation, will then give plain and umnistakabie evidence that something has been removed from or added to the goods being weighed. Various embodiments of the idea are described herein. In its preferred form the invention'inilndes what for convcnieuce mav be termed a duplex weighing-element comprising at least two members, each actuated or controlled by the weight of the gomls. The two bein capable of actuation or eontrol indepencently of each other, either may be locked without affecting the other. The locked member can then be utilized in the printing or computing operations. leaving the other free and hence capable of indicating any change in the weight of the goods on the. pan.

Several convenient and effective embodiments of the invention are illustrated in the accompanying drawings, in which,

Figure 1 is a rear view of one form of the invention.

Fig. 2 is a vertical section (on line 2-2 of Fig. 8) showing the two weighing memhers of the duplex weighing elemenLthe parallel springs which oppose the movements of the members by the weight of the goods, the scale pan connected with the members to actuate the same, and the pointers connected with the weighin members to indicate the wei ht of the g0()( s on the an.-

This figure also shows the scale and pointers as they-appear to the salesman behind the counter.

Fig. 1-1 is adiagrannnatic rear view of an embodiment in which pendulums or weights are provided to o pose the movements of the weighing mem ers by the scale pan, and Fig. 15 is a side view of the same, partly in vertical section.

Fig. 16 is a diagran'lmatic rear view of an embodiment in which springs that oppose the movements of the weighing members by the scale pair are arranged in series or in tandem iusteadof in parallel as, in Figs. 2 and 12. Fig. 17 is a side view, aartlv in vertical section, of the mechanism V which the movements of the weighing members of Fig. iii are communicated to the weigl1tindicating pointers.

Fig. 18 is a diagrammatic rear view of a tandem-spring construction employing another form of mechanism for communicating the movements of the weighing elements member or lever 23 is connected by to the pointers, and Fig. 19 is a side view, partly in vertical section, of the mechanism ust referred to.

The principle upon which the preferred form of the invention operates will be readily understood from Fig. 12, in which the scheme is illustrated diagramniatically. Referring thereto, 10 designates a scale pan, pivotally connected by a stem 11 to a scale beam or lever 12 which is fulcrumed at the point 13. At the other end, 1-1, the beam is connected by a link 15 to the center 16 of u tloatin lower member or lever 17, connected at its right end 18 to acontractile spring 1!) and at its left end 20 to a similar spring 21 through the medium of a link T 1e upper its, left end to the link 22 and spring 21, and is fulcrumed at 24; the fulcrum 24 being fixed and located directly above the point 16. At the points 25, 26, equidistant from 16 and 24, the members 17, 23 are pivotally attached to two vertical members or links 27, 28, carrying at their upper ends a pair of racks 29 30, meshing with two co-axial but independentl rotatable ears 31, 32 on opposite sides of t e latter. hese gears carry pointers 33. 3-1, traversing scale 35.

From the foregoing it is clear that when a weight is'placedon the pan 10 the same is supported by the springs-19, 21 equally; that is, each spring su ports half the weight. It is also clear that i the springs are cqllul in strength the weight on the pan will extend the .prings equally and hence the new position 0 the member 17 (indicated by the dotted line at 1?) will be parallel to the original position. At the same time, the member 23 will be rocked counterclockwise. on its stationary fulcrum 24. The racks 29, 30 will therefore impart to their gears 31, 32, movements equal in extent and the same in direction, that is. countercloclnvisc, thereby (hurrying the pointers 33, 34 in unison over the scale 35 to the positions 33', 34, for exam )lc. Either member 17, 23 can now be loctcd (for example the first named) without affecting either pointer. But suppose a change. for instance an increase, is made in the weight on the pan 10. The lever bei ng locked, the spring '21 cannot be extended farther, and the lever 17 therefore rocks on the pivot 20 as a fulcrum, sa to the position shown by the broken line 1;", and extends the spring 19. Nevertheless, the spring '19 still bears only half the weight, and since the points 25, 26' are in vertical alincmcut with the axis of the gears 31, 32. the extent of the movement imparted to the pointer 3% from its position 34' (say to the position 34-") bears the same ratio to the increment of the weight as the original movement bore to the original weight. In 'short,- thc movement of the pointer 34 is directly proportional to the weight on the pan. after the member 23 is locked. as Hence any change in well as before.

the weight after ompointer is locked is c\'ldc|i('cd by a movement of the other out first; and, in the construct movement of the unlocked pi proportional to the change of i'cgistcr with the ion shown, this nntcr is tlIl'('('il in the weight.

whether such change be positive or negative.

1 course numerous made without departing fl( the invention, as w] 1] the springs need not be of modifications can be an the spirit of be readily understood by those skilled in the art.

For example, equal strength:

in which case such alteration in the relative as may be necessarv ings and imprints. Thus i can be made f the spring 21 he the stronger, the point 16 can be shifted toward the link 2; so as to ments of the racks 29, 30 equal in extent. 0;- the gears may be of dili'erent size, etc.

A practical embodiment of the principle illustrated diagmmmaticall in Fig. 12 is shown in Figs. 1 b0 11 inclusive, in which the corresponding elements are the same numerals. In the designated by embodiment referred to,'the beam 12 is iucloscd in a base 36 having an opening 37 through which the link 15 extends into the upright housing 38 which incloses the duplex weighing element 17,

23,'and other parts of the apparatus.

The

fulcrum 21 is supported by a bracket 39, and

the springs 19, upper ends by the medium of Preferably there 21, are sup the brackets ported by their 1-0, ell, through the threaded stems 42, 43. is a scale 3-3 at both frontand rear of the housing, as shown in Fig. 5,

and the pointers are provirl ed with indexes traversing both scales, so that when the salesman and the customer are on opposite sides of the counter the movements of the indexes will be visible to both perso The apparatus illustrated as. in Figs. 1 to 11 is designed to'print the weight on a suitab' 3 check for delivery to the cu this purpose the following in vided.

(in the shaft 44 (Figs. 3

stomer, and f( r cchamsm is roand 8) parallel to the axis of the gears 31, 3:2. (Fig. 12) is a lever 45, carrying at its up shaped member or printin which are characters for similc of the scale 35, and

' is a fixed character or type a pointer or index.

tor 46 is shifted past the im with the pointers 33, so as t readingas the pointer 33 gi 35. By means of an Ink ril pcr end an arcg sector 4-6 on printing a facbclow tllt' sector 4-? for printing The swinging scale-Seclcx 47 in unison o give thesame \('.s on the scale )hon and a suitable platen a check can then be printed,

from which the weight can 1 scale 35. Fig. 13. The words \Vcig chase or any other desired in read as on the Such a printed chm-k is shown in ht of your purwords 01 charactcrs can be printed on the check by pro- \itling suitabl type therefor, preferably carried by the member 48 that supports the index type t7. This member 48 is carried on the upper edge ofa bar 49 (see also Fig. in) fixed across the small chamber .30 formed in the rear wall of the housing 3H.

The lever is rocked to set the printing sector -16 by a link 51 connected with an arm .32 coaxial with the gear 31 but movable independently thereof. Fixed to the. gear 31 is a friction disk or annulus 53 having an arm 54, to which the pointer 33 is conveniently attached as clearly shown in Fig. This arm carries a stop 55 to cooperate witha similar stop 56 on an arm 57 rigidly connected with the arm 52.

The foregoing parts being properly proportjoned. it is clear that if the disk or annulus .33 and arm 54 are locked after the. pointer 33 comes to rest and the arms 5? are rocked (counterclockwise as seen in Fig.

3) the latter will eventually be arrested by the cooperation of the stops 55, 56. with the sector 46 properly setfor printing the weight indicated by the pointer 33 on the scale 35. This locking of-the arm 54 is effected by a clamp,fiat-(imposed oftwo me m-' hers pivoted on a bracket (50 (Fig. ti) and having friction 'jaws {i1 embracing the edge of the disk or annulus so that when the opposite ends of the members are spread apart the jaws will grip the annulus and hold the same firmly. 'The spreading or actuation of the members aais effected bv'a quadrant-cam 62 fixed on a shaft (33 (Fig.

it) which is rocked by a suitable operating handle 64 (Fig. 8) through the instrumentality of a rock-shaft (35 and bevel gears 66. (37. F iked on the shaft (:3 is an arm ttS. con nected by a coil spring 69 to an arm Tfi loose on the same shaft. which spring serves to hold the last named arm normally in the position shown in Fig.-3 with respect to the, arm 68. with the abutment or stop 71 against the tinger 72. The arms and 57 are con net-ted by a link T3.tbe connection with arm 70 being made by a slot 74 in the link. It. will therefore be seen that when the handle (H- is rocked the first efi'ect is to lock the disk 53 and arm '54. During this operation thestud on the end of arm 70 movesidly through the slot 74. but when the locking operation is completed the stud reaches the end of the slot. and the further movement of the arms fits and 70 then swings the arms 57. until the same are arrested by the stop as previously described. Further movement of the operating handle (54 then separates the arm as from the arm 70. extending the spring '69. 'hen the handle is released by the operator a spring 75. Figs. 2 and restores to individual position the parts actualcd by the handle.

After the printing sector I6 is set as the scribed in the preceding paragraph the printin is cti'ectcd by the following mechani m. The platen To is fixed at its lower end to a short shaft which atone end has fixed to it a forwardly and downwardly extending arm 77 (Fig. (3) having a roller 78 held against a quadrantal cam 79 on the shaft 65 by a spring 80. \Vhile the shaft. (if) is being rocked by the handle (it to lock the controlling arm 54 and set the sector 46 the concentric portion of the cam moves.

idly past the roller 78; then the rise at the upper edge of the cam reaches the roller and swings the platen clockwise (as seen in Fi". a). thereby pressing the )aper check-strip 81 and the ink ribbon S2 hrmly against the sector 46 and index-type 47. Upon release of the handle the springs and restore the cam and the platen to their initial positions.

The ink ribbon 82 is carried by two spools R3. 84. Fig. 8, and fed from one spool to the other by any suitable mechanism not shown.

The paper check-strip 81 is drawn from a u'oll 85. Fig. (3. rotatably supported outside the housing 38, and passes between two guide rollers 86 and through a guide chute latter rollers are geared together at one end, as shown in Fig. R. and at. the other end the roll SH is provided .with a bevel gear 90 meshing with a similar gear 91 (Fig. 10) on a short shaft 9:2. The shaft. 92 is geared to the shaft 93. which is alined with the shaft fl-t (Fi 2) and carrying a two-toothed ratchet 95, Figs. 8 and 11. ()n the shaft 94 is an arm 96 carrying a pawl 97 engagin the ratchet. and the shaft also has a spire. gear 98 meshing with a similar gear 9!) on the shaft (55. 'hile the operator is rocking the handle (i-t to its extreme position, the arm 96 is rocked clockwise (as seen in Fig. 11), thereby retracting over the ratchet the pawl 97 which moves in a plane adjacent to that of the spring holding pawl 100. Finally the pawl 97 engages the lower tooth of the ratchet. Then when the shaft 65 is rocked by the spring '75 the pawl 97 is ad vanced. thereby rotating the ratchet a half turn and rotating the feed rollers 88, 89, through the mcdimn of the gearing described. The printed portion of the checkstrip is thus fed up through the slot lti'l in the top of the chamber 50 and is torn off against the serrated 'edge ofthe slot for delivery to the customer. leaving a fresh portion of the check-strip in position for the next operation of the machine.

Figs. 14 and 15 show a convenient and simple method of embodying the invention in a scale of the socalled pendulum type, wherein the scale pan is balanced against a swinging weight. In the figures referred b0, the scale pan 102 and scale beam 103 are connccted by a link 104 to the lower member 87 to the friction{feed-rollers S8, S9. The

105, which is connected at its left end by a link 100 to the upper member 107. .\t the right. the two members are connected by suitable straps 108, 109 to the pendululns 5 110. 111, respectively. In Fig. It the two weights or pendulnms are directly in line and hence only the one in front, designated by 111, can be seen, but both are clearly shown in Fig. 15. The pointers 112, 113 are connected to the pendulums 110 and 111 respectively, t-he.last named pointer through the medium of the clutch disk 11-L on which it is mounted and by which the member 107 and weight 111- are locked through the me- 15 dium of suitable devices such, for example, as those shown for a similar purpose in Figs. 3 and 8. Inasmuch as the weights swing in circular arcs, the force exerted upon'them by gravity and eiliectively opposing'the force exerted by gravity on the goods in the scale pan varies as the cosine of the a le between the center of gravity of the weig its and the horizontal, measured on an arc whose center is the axis of the pendulum. Hence, in 5 order that the divisions of the scale may be uniform tlu-oughout, the straps are wound not upon cylindrical surfaoes'hut on camshaped members. 116, 117; As the precise mmtilc-eurvature that theseanembers must lave for the purpose is well'mnderstooidiit, -nced not be discussed herein. In the construction illustrated in Figs. 14 and 15, it is clear that if the parts are so designed and proportioned as to cause the pointers to move in unison when the member 107 is free the locking of'this member will have no elifect upon the pointer 112, actuated by the other member, 105. Hence any change in the weight on the pan after mem- 40 her 107 is locked will be indicated by the pointer 112.

The arm 118 of the clutch disk 114 is provided' with a stop 118' for the same purpose as the similar stop 56 in Fig. 3, namely, to determine the setting of silitable'frinting mechanism or other devices. hinting mechanism like that illustrated in Figs. 3 to 10 inclusive may housed, and illustration of the some in connection with'Figs. 1-1 and 15 so is therefore unnecessar In the construction shown in Fi 10 and 17 two springs, 119, 120, are emp oyed, but are arranged in series or tandem instead of in parallel as in Fig. 12. \Vith tandem springs it is clear that the lower endof the lower spring will sink farther under the influence of a given weight on the pan than will the lower end of the upper, the ratio being 2 1 if the springs are of equal strength. Compensation for this inequality of movement can be made in various ways, as for example in the manner illustrated. I lore the cmploymentof a floating gear 121 meshing with racks 122, 123, connected with the members 124. 125, and itself connected (as through the medium of the link 120 and lover l2i' with the rack 128 to actualc the latter. transmits the movement of the lowcl end of spring to the rack 12%. and the. rack 129 is actuateddirectly by the member 125. With the parts proportioned as shown, the movement of. the rack 128 is somewhat less than half as fast as that of rack 129. The diameters of the gears 130. 1 31 are therefore in the same ratio as are the movcment of their actuating racks, with the result that thc'pointers 132. 1253. connected with the gears 130, 131. respectively. move in unison when the members 124. 12.") are both free. If now the member 125 be locked by means of the stop disk [34 (connected with the gear 131 and carrying the stop arm 135 on which the pointer 133 is mounted) the lUWcl' end of spring 120, the upper end of spring 119. and the racks 123. 129. are thereby fixed. Hence any change in the weight on the pan will cause a change in the extension of the spring 119 only. This extension increment (negative or positive. according as weight is removed frouror added to the pan) will move the rack 1:22 only half as far as would ,be the case if the spring 120 were free. But Since the rack 123 is stationary. the movement imparted to the gear 121 and rack 12s by the weight increment hears the same raho to the original movement of the parts mentioned as the weight-incrcniem hours to the original weight. In short the pointer 132 will indicate the correct weight of the goods on the )an even after the member is locked. n mathematical language. it with both members 124 and 125 free a weight '1! moves rack 122 a distance a. rack 123 will move a distance .c/2; and since the vertical movement ot the gear 121 is alwavs half the difference of the movements of the racks the gcarwill move up a distance .r 4. \ssume now that the member 12.": is lnt'lttd and that the weight on the pan is increased to. sa v 2a. The weight-incrcmcnt is therefore -u. if the spring 120 were free to stretch. the rack 122 would move up a further distance 1 but since spring, 1:20 cannot stretch, the further movenn-ut of rack 122 is only .r/2. The additional movement of rack 123 being zero. the additional vertical movement of gear 121 is (.1"2(l) 2:..12/4. It is therefore seen that the movement imparted to rack 12h aml gear by a given weight is not varied by locking the member 125. aml that any change in the weight on the pan after member 125 is locked will be corrcctlv indicated by the pointer 132 if the original weight were correctly indicated thereby.

It will be understood that the movement of the rack 12?- undcr the influence of a certain weight depends not only upon the ratio of the strengths of the springs but also upon the ratio of the lovers to which racks 122 and 123 are connected. and upon the ratio of the arms of the lever 127 In the example given above, it was assumed that these ratios are all unity. Thus, if in lever 12? the arm to which link 126 is connected be reduced relati rely to the other, the movement of rack 128 will be increased and the diameter of gear 130 must -be correspondingly increased to make the pointer 132 move in unison with the other. Similarly, if the fulcrum of lever 124 be shifted toward the right, thereby diminishing the upwardmovement of the rack 122 for a given weight, the change can be compensated by shifitm the fulcrum of lever 125 toward the ri t to produce a suitable diminution of the movement of rack 129. These and other changes, however, are well understood by persons skilled in the art and therefore need not be elaborated herein.

In Figs. 18 and 19 the lever 136 and 137. to which the tandem spri 138, 139 are at tached, are both connects directly to the racks 140, 141, which actuate the gears 142, 143 and pointers 144, 145. '-Hence the rock 140 will move farther under the influence of a given weight than will the rack 141. The difi'erence can be'compensated for' preferably by the method illustrated. Here the scale 146, which the pointer 144 traverses, is carried by the 'nter 145 and hence moves therewith. onsequen-tly the scale mentioned is stationary relative to the pointer 144. Thus, assuming that the springs are of equal strength, that the levers 136 and 13-7 have the same arm-ratio, and that the gears 142', 143 are of the same diameter, the angular movement of pointer 145 will be just twice that of pointer 144 for a given weight when both springs are free. The result is that if pointer 144 swings one degree the pointer 145 will swing two; but the scale 146 will also have moved one degree and hence the movement of pointer 144 relative to its scale will be ohe degree. In short, the reading on scale 146 will be "a same as'on scale 147; assuming, of course that the two scales are properly proportioned. In the drawing the scale 146 IS nearer the axis of its pointer than is the other scale and hence its divisions must be smaller in the'same ratio. Onthe other hand, when the lever 137, s ring 139, pointer 145 and scale 146 are loc ed, as by means of the disk 148 connected with the gear 143, the upper end of spring 138 becomes fixed and its lower end will therefore have proportionately less movement for any change in the weight than it would have if spring 139 were free. The movement of pointer 144 relative to the now stationary scale 146 will, for a given chan of weight,

therefore be the same as it wo-u d be if both springs were free and scale 146 moving. The reading on scale 146 is accordingly correct whether spring 139 be locked or not,

' It is of course clear that theiprinting mechanism illustrated in Figs. 3 to 10 inclusive can he used with the constructions weight indicating means and, the intermediate actuating mechanism therefor being at all times free to operate, and means for locking the other weight indicating means and the intermediate actuating mechanism therefor. in the position to which it was brought by the weight originally placed in the pan.
